摘要
描述了聚合物共混物及纤维增强聚合物基复合体系的内耗研究现状，并着重分析了内耗行为与微观结构的相关性。指出内耗特征可在分子水平上反映共混物组份间和复合材料界面间的相互作用，并因此而成为研究共混物超分子结构和复合材料亚微界面结构的敏感而有效的表征手段。目前迫切需要解决的问题包括对内耗微观机制的研究，建立起适当的模型，并赋予特征参数以明确的物理意义。
The paper represents the situation of internal friction researches for polymer blends and composites,and analyses specially the correlation between internal friction behavior and microstructure.It is found that both intermolecular interaction in polymer blends and composite interface interaction are reflected by internal friction features at molecular level,therefore,internal friction measurement is sensitive probe for characterizing supermolecular structure in polymer blend and composite interface microstructure.The intrival problem needed to be considered in the future includes the studying of internal friction mechanism,establishing appropriate model to describe the internal friction behavior and giving definite physical meaning for characteristic parameters.
